A valid signature proves record integrity, not identity, attendance, or time worked. Review observations alongside the worker's account.
Door activity was observed at Alvarez residence from 6:31 PM to 7:36 PM, spanning about 65 minutes. The link issued to Maria Chen was used to self-report presence at 7:36 PM; identity was not independently verified. These observations do not establish departure, continuous presence, or time worked. Review notes: Record closed for review; direction, identity, and continuous presence are not established; Observations span 65 min; 90 min scheduled. Time worked is unknown.

| Pipeline coverage | watched — events seen | 32% of window · 6 polls | How much silence is meaningful vs. unwatched |
| Source divergence | 65 min apart | first device observation vs. worker check-in (check-in later) | Discrepancy to review — neither source is authoritative |
